New Delhi (Agencies): Rejecting the arrest of former IT and Communications minister A Raja 'too little, too late', the Bharatiya Janata Party (BJP) on Wednesday said its demand for a joint parliamentary committee (JPC) into the 2G spectrum allocation scam still stands.

'Well, the spectrum allocation to the favourites of the minister and understated value took place in 2007-08. We are now in 2011 and you obviously have a situation more than two years...this government did nothing despite the issue raised by the media and opposition. Why was Prime Minister in the denial mode all this time?' BJP leader Arun Jaitley said, speaking to reporters here.

He alleged the government covered up the scam for two-three years, and even as late as a fortnight ago Raja's successor Kapil Sibal was trying to market a theory that no loss took place.

'Any action of this government will not arouse any element of confidence. Opposition is not satisfied and we will continue with our demand of JPC on 2G spectrum. The government has taken action only after pressure from Supreme Court and media,' he said.

Ties with DMK intact: Cong

Congress, meanwhile, said the arrest of Raja was a case of law taking its own course.

"Congress had said earlier also that all such cases should be investigated and enquired properly and law will take its own course," AICC General Secretary Janardhan Dwivedi told

He said the development would not have any bearing on the relations between the Congress and DMK, to which Raja belongs.

Raja's arrest does not affect PM's credibility: Cong

Dismissing suggestions that the arrest of former Telecom Minister A Raja in the 2G spectrum allocation scam would affect the credibility of Prime Minister Manmohan Singh, party spokesman Abhishek Singhvi told a mediapersons that," Apart from you, there is no one in the world who will say that the credibility of the Prime Minister or the government is affected. It has allowed the law to take its own course, independently and objectively."

He also brushed aside AIADMK supremo J Jayalalithaa's demand that the entire family of Tamil Nadu Chief Minister and DMK supremo M Karunanidhi be arrested following the action against Raja. "You cannot start criminal proceedings against anyone just because someone has made a demand".
